Table 1. Estimated Full Range Pressure Adjusting Time (seconds) 12 VDC Supply
GENERAL INFORMATION
The DC Pulse Input unit allows incremental adjustment of
regulator output pressure and provides for various
adjustment times for full range operation.
The DC Pulse Input unit contains a Clock Generator/
Translator Board which allows for operation with a
12 VDC or 24 VDC pulse input signal for use with an
External Controller with a 12 VDC or a 24 VDC output.

Figure 1. Clock Generator PC Assembly
Remove power from unit when changing
SW1-2 from half step mode to full step mode:
Switching from half step mode to full step
mode when the power is on can result in
motor operation at 1/2 its torque capability.

6.
Turn the Normal/Slow Switch (SW1-3) to the Off/
Open position to achieve adjustment of pressure
over the full range when the stepper motor is
running at high speed.
Adjust the R11 Speed Control to fine-tune the
adjustment time. Refer to the column “High” of the
appropriate table on page 1 for the specific regula-
tor model and pressure range.
Turn the Normal/Slow Switch (SW1-3) to the On/
Closed position to achieve adjustment of pressure
over the full range when the stepper motor is
running at low speed.
Adjust the R11 Speed Control to fine-tune the
adjustment time. Refer to the column “Low” of the
appropriate table on page 1 for the specific regula-
tor model and pressure range.

7.
Turn the Externally/Internally Switch (SW1-1) to
its appropriate configuration in accordance with
how the customer has his controller wired to the
Clock Generator Board. For more information,
see Figures 2, 3 & 4 below.
Additional Adjustments
Limit Switch Adjustment
Adjust the Low and High Limit Pressure Switches by
removing the Motor Assembly Cover and tuning the adjust-
ment screw on the top of the Motor Assembly. Decals
indicate the direction in which to turn the screws to change
the High and Low output limit pressures.
